GOGGLES OR EYE-PROTECTORS.

Specification of Letters Patent.

Patented Feb. 26, 19153.

Application filed October 23, 1915. Serial No. 57,591.

To all whom it may concern."

Be it known that I, J OHN U. BARR, a citizen of the United States, residing at New York, in the county and State of New York, have made a certain new and useful Invention in Goggles or Eye-Protectors, of which the following is a specification.

This invention relates to goggles or eye protectors.

The object of the invention is to provide goggles or eye protectors which are simple cient.

A further object is to provide goggles or eye protectors which in one portion thereof afford protection to the eyes of the wearer against the dazzling and blinding efiects of brilliant light without destroying vision through such portion, while at the. same time, in another portion thereof, affording a restful protection to the eyes .for use in ordinary light without impairing the vision through such portion.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination and arrangement, all as will be more fully hereinafter set forth, as shown in the accompanying drawing, and'finally pointed out in the claims.

In the drawings: a Figure 1 is a view showing'a goggle em- Fis. 2, 3, and 4, are views of use in goggles and embodying my invention.

In carrying out my invention I employ transparent material, such as plain glass, mica, celluloid, or the like, of substantially uniform thickness throughout and :cut or formed to the desired shape and contour to be fitted into a smaller frame for use.

i shall refer to a single piece of such material throughout, and, in accordance with my mso cut and formed, as a glass, intending, however, by such term to include not only plain glass, but also mica, celluloid or other suitable transparent material.

I propose tense plain glass or other transparent material of substantially uniform thickness, and in one piece, which is or has been, uniformly tinted, shaded or colored I construct one portion of such vention,

a'deeper or darker tint, shade or glass with color than another portion thereof," and pref- 'erably the darker colored or shaded'portion glasses for I 'oient for useby automobilists,

gle. piece, 0

is sharply defined from the lighter colored or shaded portion.

In the drawlng the single piece of plain transparent material, of substantially uniform thickness has one portion A thereof uniformly colored, shaded or tinted to a greater density than the portion 13 thereof,

which portion B, however, in accordance with my invention, is also tinted, shaded or bottom, or through the middle of the glass.

In Fig. 2 the darker portion A is the top portion. In Fig. 3 the two portions are defined from each other-along a curved line.

In Fig. 4.- the lighter portion'is through the middle of the glass, the upper and lower portions being more deeply colored.

A pair of glasses constructed as described, andfitted to a usual and suitable goggle frame C, afi'ords an eflicient protection for the eyes against blinding or dazzling lights, through the darker colored portion, and

against ordinary light through the lighter colored portion, without, in either case interfering with the vision through the transparent glass. gradually varying gles constructed adaptedfor general densities of shade. Gogas described while well use are particularly efiiparticularly at night time to prevent the eyes from being blinded by the dazzling head lights of an approaching machine.

The eye is-not strained by I am aware that it has been proposed to construct goggle glasses with one portion colored or shaded and another portion clear and colorless, and I make no claim to such a device. 1

But having nature of my invention now set forth the objects and and a construction embodying the principles thereof, what I'- claim as new and useful, and of my owninvention, and desire to secure by Letters Patcut, is,

1. A goggle having glasses each of a single piece of transparent material of substan tially uniform thicknes, and colored or shaded throughout, and having one part more deeply colored or shaded than another p 2. A gogigle having glasses each of a sintransparent material of substan-- tially uniform thickness, and colored or my hand in the presence of the subscribing shaded throughout, and having one part witness, on this 20th day of October, A. D. more deeply colored or shadgd than angther 1915. part t e more deeply sha ed part eing r, sharifly defined from the lighter shaded JOHN BARR part. Witness:

In testimony whereofI have hereunto set S. E. DARBY.
